Workout Regiment Advice

I work out 6 days a week for about 1 hour a day.
Gradually moving up in weight with each set

The first day is chest and abs

Dumbbell Flat Press: 4X10,8,8,6
Incline Bar Press: 4X10,8,8,6
Decline Bar Press: 4X10,8,8,6
Dumbbell Flies: 4X10,8,8,6
Machine Flies: 4X10,8,8,6
100 inclined crunches
50 inclined crunches wearing 20lb weighted vest
30 leg ups
Weighted side ab workout

Second Day biceps and shoulders

Dumbbell Shoulder press 4X10,8,8,6
Dumbbell Shoulder Lifts 4X10,8,8,6
Eagles 4X10,8,8,6
Machine Shoulder Press 4X10,8,8,6
Dual Dumbbell Bicep Curls 4X 20,15,10,8
Straight Bar Bicep Curls 4X10,8,8,6
2 sets of twenty bicep pull ups with 20lb weighted vest
Seated ramped dumbbell bicep curl 4X10,8,8,6

Third Day triceps and back

Skull Crushers 4X10,8,8,6
Standing Skull Crushers 4X10,8,8,6
2 sets of 20 dips with 20lb weighted vest
Triceps push down 4X10,8,8,6
2 Sets of 20 back pull ups with 20lb weighted vest

Forth day is legs

Squats 4X10,8,8,6
Various machines that I am not sure about but having to deal with leg workouts.

The Fith Day is a rest day then I would start the process over after my rest day.
I am concerned that my regiment between days is too stretched out. Like for example I dont feel like I should go 5 days without doing chest until the next cycle.
